URLRequest to other domain results in Sandbox Violation

I am trying to access a URL generated at runtime of my swf (“http://www.yourdictionary.com/synonyms/"+synVariable+".html”) using URLRequest. It works fine when I test from within flash CS5 pro but when I host to my server, I get:

Error #2044: Unhandled securityError:. text=Error #2048: Security sandbox violation: http://publish.uwo.ca/~kfieldi5/synonymGen/antGen.swf cannot load data from http://www.yourdictio

Any way to get around this error?

Thanks in advance,
Kevin
